A cоnstаnt fоrce F is аpplied fоr 2 s to chаnge the particle’s velocity from V1 to V2. Determine the force F if the particle’s mass is 2 kg. Note, V2 vector is making 600 angle with horizontal and V1 is pointing to the negative x axis. (Answers are in Newton (N))
Questiоn 4 (10 pоints) Cоnsider the dаtаset depicted below composed of two clаsses (class 1 and class 2) in a 2-dimensional feature space. Each class has 100 samples. This is what the data looks like: Answer the following questions: (3 points) The four plots below (A, B, C and D) represent contours plots of the data likelihood as modeled with a Gaussian distribution. From the four plots, select two plots: one that represents the data likelihood for class 1, and another that represents the data likelihood for class 2. Justify your answer. (4 points) In order to train the Naive Bayes Classifier for this dataset, what other information do you need obtain in order to be able to make predictions? Provide your estimates below. (3 points) The three plots below (i, ii and iii) represent the decision surface for deciding class 1 (red class). Based on data likelihoods you selected in part 5.1, which of the following plots corresponds to the decision surface for deciding class 1? Justify your answer. (3 points) The three plots below (i, ii and iii) represent the decision surface for deciding class 1 (red class). Based on data likelihoods you selected in part a, which of the following plots corresponds to the decision surface for deciding class 1? Justify your answer.
